Who We Are

Local Waterproofing Specialists Who've Already Seen Your Problem Before

Every SGP Waterproofing technician working in Kewaskum, WI carries the same licensing, the same insurance coverage, and the same set of tools whether the job is a single cracked footing or a full interior drainage system. We built the company on the idea that a homeowner shouldn't need three quotes and two weeks of waiting to get an honest answer.

Because we staff locally instead of subcontracting out to whoever's available, the estimate you get over the phone tends to match the invoice you get at the end of the job — no surprise line items, no upsell script.

  • On call every night of the year, not just business hours
  • Written quotes with no hidden change orders

Older Kewaskum, WI neighborhoods often have block foundations poured decades before modern drainage codes existed, while newer subdivisions tend to run poured concrete with a perimeter drain that was installed correctly but has since clogged with silt. Knowing which era of construction you're dealing with changes the repair plan before a single tool comes out of the truck.

We also see a lot of properties where a previous waterproofing attempt only addressed the symptom — a topical sealant painted over a cracked wall, for example — without solving the pressure or grading issue causing the crack in the first place. Part of every Kewaskum, WI inspection is checking for that kind of prior patch job before we recommend anything new.

Problem Signs

Six Warning Signs Your Kewaskum, WI Property Needs Waterproofing

Most Kewaskum, WI water intrusion problems don't start as a flood — they start small, and they get worse on a schedule. Here's what our technicians look for on a first inspection.

Sign 01

Musty Basement Odor

That damp, earthy smell in a finished or unfinished basement is usually mold or mildew feeding on moisture that's already gotten past your walls.

Sign 02

White Powdery Efflorescence

Efflorescence forms when water carries dissolved minerals through porous concrete and leaves them on the surface as it dries — a clear sign moisture is actively passing through.

Sign 03

Hairline Wall Cracks

Small stair-step cracks in block walls or vertical hairline cracks in poured walls tend to widen over a season or two as hydrostatic pressure keeps pushing.

Sign 04

Damp or Bubbling Drywall

Drywall that feels soft, bubbles, or shows a tide line near the floor is already absorbing groundwater — by the time you see it, the insulation behind it is usually soaked too.

Sign 05

Window Well Flooding

A window well that fills with water during heavy rain is putting direct pressure on the glass and frame, and it's one of the most common entry points we find in older Kewaskum, WI homes.

Sign 06

Standing Water After Storms

Puddling near the foundation that doesn't drain within a few hours usually means grading, gutters, or a failing perimeter drain — and it's the fastest path to a flooded basement.

What We Do

The Waterproofing Work Kewaskum, WI Property Owners Call Us For Most

Every job starts with the same on-site inspection, whether it's a single crack or a full interior drainage retrofit. Below are the services Kewaskum, WI clients request most often.

Emergency

Emergency Waterproofing & Flood Response

Once the water is out, we run air movers and dehumidifiers to bring humidity down before mold has a chance to establish itself in drywall or subfloor.

Residential

Residential Basement Waterproofing

Most Kewaskum, WI basements need a combination of interior drainage and a properly sized sump pump — we size the system to your square footage and soil type, not a one-size-fits-all package.

Commercial

Commercial & Multi-Unit Waterproofing

Parking garages, below-grade retail space, and multi-family basements need waterproofing membranes and drainage systems rated for continuous traffic and higher hydrostatic load.

Foundation

Foundation Crack Repair & Injection

If a wall is bowing rather than just cracked, we'll flag that during the inspection since injection alone won't address a structural deflection issue.

Crawl Space

Crawl Space Encapsulation & Sump Systems

A properly encapsulated crawl space with its own sump discharge line keeps humidity below the threshold where wood rot and mold can take hold.

Drainage

Exterior Grading & French Drain Systems

Sometimes the fix isn't inside the wall at all — regrading the soil away from the foundation and adding a French drain can solve a moisture problem before water ever reaches the block.

How It Works

Our Four-Step Waterproofing Process in Kewaskum, WI

01

Call & Phone Assessment

A dispatcher walks through symptoms with you on the phone so the crew that shows up already has a rough idea what they're dealing with.

02

On-Site Inspection

We walk the interior and exterior with a moisture meter and flashlight, tracing water back to its actual entry point instead of guessing.

03

Written Quote

We put the scope, materials, and price in writing so you can compare it against anyone else's estimate line for line.

04

Installation & Walkthrough

Most residential jobs finish in one to three days, and we walk the property with you afterward to confirm every drain, pump, and seal is working.

FAQ

Waterproofing Questions We Hear Every Week in Kewaskum, WI

How fast can a Waterproofing technician arrive in Kewaskum, WI?

Response time depends on call volume and severity, but emergency water intrusion always jumps the queue ahead of routine estimates.

Do you provide upfront pricing?

Yes — every job gets a flat-rate, written quote before work begins, and that number doesn't change once the crew is on-site.

What emergency services are available?

Our emergency response covers water extraction, temporary pump-outs, and emergency crack sealing to stop active intrusion until permanent repairs are scheduled.

How much does basement waterproofing typically cost?

Pricing varies with scope, but every Kewaskum, WI customer gets an itemized written estimate before any work is authorized, so there's never a guessing game.

Will you repair hairline foundation cracks or only large cracks?

Hairline cracks are actually the ideal time to call, since injection repair is faster and cheaper before hydrostatic pressure has a chance to widen the gap.

Do you offer interior or exterior waterproofing systems?

The right system depends on access, budget, and what's actually driving the water in — we'll explain the trade-offs before you decide.

How long does a typical waterproofing job take?

A single crack injection can be done in an afternoon, while a full interior drainage system typically runs two to three days start to finish.

Do you work with insurance claims for water damage?

Documentation from our inspection often helps speed up the claims process, but final approval is always the insurer's call.

Is a sump pump necessary if I already have a French drain?

In most cases yes — a French drain collects water, but it still needs a sump pump to actually move that water out and away from the foundation.

Do you offer a warranty on your waterproofing work?

Yes, every interior drainage, sump, and crack repair job comes with a written warranty, and terms are explained in full before you approve the quote.

Can you waterproof a crawl space with standing water already present?

We assess the water depth and source first, since active groundwater intrusion changes how we sequence the encapsulation work.

Do you service commercial properties as well as homes?

Yes — our commercial work covers parking garages, retail basements, and multi-family buildings, usually scheduled in phases to minimize tenant disruption.
